It was the third summit between the two Koreas following meetings between Kim's late father Kim Jong Il and late South Korean presidents Kim Dae-Jung and Roh Moo-Hyun, in 2000 and 2007 respectively.

Mr Dae-jung won the Nobel Peace Prize in 2000 for his role in the first summit. Mr Moon's comments came in reply to Mr Dae-jung's late widow, who said she hoped the current South Korean president could also win.

Friday's meeting between Mr Moon and Kim is being hailed as a major step toward easing tensions and is said to set the tone and for the first face-to-face meeting between Kim and Mr Trump.

Just a few months ago the hopes of such a meeting with nuclear-armed North Korea were almost unimaginable. Insults flew across Twitter timelines as Mr Trump and Kim traded names like “Rocket man” and "Dotard"and the US president promised “fire and fury".

The fears of conflict have since cooled off in light of the peace talks and a new promise from the North to shut down nuclear testing sites.

On Saturday, Mr Trump stood in front of supporters who were chanting “Nobel! Nobel!” in a campaign-style rally in Michigan, as he trumpeted his ability to achieve a nuclear deal with Kim.

The Nobel Peace Prize is set to be announced in October. UK bookmaker Coral favours Kim and Mr Moon to win (odds of 4/6) over a tie with Trump and the UN High Commissioner for Refugees (odds of 10/1).
